wierd dns / dhcp issue...

I have 2 windows server 2003 machines that are running dns and dhcp. I also have a linux firewall/gateway.

When a client logs in the dhcp server assigns a correct ip address, dns addresses and default gateway address.

At least twice per day the client computer will suddenly lose internet connectivity.

Upon the command ipconfig /all ... both dns addresses have changed to the default gateway address!?

If I release and renew all is back to normal. My entire office is having to release and renew at least twice per day.

This happens sporadically and I can't seem to put my finger on what is happening.

Any suggestions?

Are you running DNS and DHCP on the two seperate machines? Or are DNS and DHCP on both machines?

Do your computers have wireless enabled? Are there possibly any competing networks around that your computers might be auto-connecting to? Does your default gateway address point to the Linux gateway? Do your DNS servers have the same configuration?
